Conventional authentication systems verify a user only during initial login. Active authentication (AA) performs verification continuously as long as the session remains active. This work focuses on using behavioral biometrics, extracted from keystroke dynamics, as “something a user is” for active authentication. The proposed scheme performs continual verification in the background, requires no additional hardware devices and is invisible to users. Research results from this project are summarized in this talk. The demonstration of a prototype system developed at ISU with collaboration from Princeton is also included in this talk.
